Column Chromatography
Source Institutions
In this activity, learners separate the components of Gatorade using a home-made affinity column.

CD Air Puck
Source Institutions
In this activity, learners will use a compact disc to build an air puck that can glide across a smooth tabletop. The puck glides with almost no friction on a cushion of air escaping from a balloon.

Size and Distance
Source Institutions
In this activity about depth perception, learners create an optical illusion in a shoe box.

Chilean Sea Bass: Off the Menu
Source Institutions
In this data analysis activity, learners use data collected by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) to study Chilean sea bass populations.

Don't Be Nerve-ous
Source Institutions
In this activity, learners discover a brain process called habituation.

Getting Your Bearings
Source Institutions
In this activity, learners explore the concept of friction and how ball bearings reduce friction.

Making Sense of Sensors
Source Institutions
In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

Pendulum Snake
Source Institutions
In this physics activity, learners assemble and/or investigate a pendulum "snake." Several large steel hex-nuts are suspended on strings of successively increasing length to form a series of pendulums

Fish Wheels
Source Institutions
In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur

Antibody Builder
Source Institutions
Learners use Duplo bricks to build antibodies with shapes that match model viruses.

Equatorial Sundial
Source Institutions
In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

Telescopes as Time Machines
Source Institutions
This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.

Irrigation Ideas
Source Institutions
In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.

How Our Environment Affects Color Vision
Source Institutions
In this lab (Activity #1 on page), learners explore how we see color.

Coral Snapshots: Biodiversity in Marine Protected Areas
Source Institutions
In this data activity, learners analyze data from coral reef snapshots taken by scientists at the Virginia Institute of Marine Science.

Biological Succession in a Microecosystem
Source Institutions
This laboratory activity helps learners understand the concept of biological succession by simulating the process in a microenvironment with various protozoans.

Paper Cup Stool
Source Institutions
In this activity, learners will explore how and why weight distribution works.

Personal Fan
Source Institutions
Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.

To Topo Two
Source Institutions
In this activity, two groups of learners create two separate landform models out of clay (mountains and valleys).

Auditory Acuity
Source Institutions
This activity (8th activity on the page) tests learners' ability to identify things using only the sense of hearing.
